Meet the Sea cucumber.
There are over 1,200 known species and they come in a variety styles and looks. Sea cucumbers feed on tiny particles like algae, tiny aquatic animals or waste materials.
They are also enjoyed by humans, especially in Asia, where some species are farmed as delicacies.
A sea cucumber doesn’t feel fear or has any memory — in fact, it has no brain. In the presence of danger, some species will expel their toxic internal organs.
The process is called evisceration.
Their muscles contract and shoot out their intestines as a defense mechanism but they also expel their guts just to clean them, too.
